Bubble on map with Google maps

Hello
Is it possible to make bubbles on a map with Google maps
Something like in the picture below

Thanks for your responses

Are you specifically tied to using Google maps? If not, this may be a good alternative to do what you want: Leafy Maps 🌿 (new free plugin)

Thanks!!

Yes you can. Just need to load them as customized icons. Not sure about getting the numbers though.
